Abstract

"ISOLADOR DE MANCAL COM PURGA DE AR". A invenção descreve um selo aperfeiçoado, utilizando uma purga de ar para remover contaminantes. O selo (1) é mais útil em hastes (10) e utiliza uma combinação de anel de travamento e anel difusor (18), para difundir o ar dentro do próprio elemento selo (1). O ar pressurizado é passado do difusor (18) para pelo menos uma cavidade ou câmara (31), que está dentro do rotor do selo (1) e que, em virtude da sua rotação com o rotor, proporciona um efeito centrífugo, para remover, eficiente e completamente, os contaminantes, incluindo o líquido ou o ar e evitando, assim, que os contaminantes atinjam os mancais, que o selo ou o isolador de mancal está protegendo. O elemento isolador de mancal ou selo vai operar, eficientemente, com ou sem pressão de ar, mas opera mais eficientemente com uma pressão de ar muito pequena aplicada ao difusor (18) e ao elemento de travamento.
